I do my game development on Ubuntu Linux. In case you hadn’t noticed, unlike pretty much every Linux distro, Windows does not come with Python installed by default. For distributing games written in Python on Windows, it’s nice to create a compiled executable version (using py2exe or cx_Freeze, for example) that can unzipped or installed with two or three clicks, without requiring a separate Python installation. Gamers will typically give up if they have to go on a wild goose chase to install Python, Pygame and maybe something else just to get your lame game to run. (Hey, that gives me an idea for a great game – “Software Dependency Wild-goose Chase”. Actually, it would probably be un-fun. Scrap that idea.)
